This is a glass made from a recycled wine bottle. It has two indentations, making it easy to grip with your fingers. The color is a characteristic yellowish-green transparent of recycled glass. There are no cracks, but as shown in the last photo, small scratches are visible when held up to the light. I have used it as a glass, but it might also be usable as a vase. Recycled glass, Ryusei glass
